In the cement production line, producing 1 ton of Cement need grind at least 3 tons of materials (including raw materials, fuel, clinker, mixed materials,gypsum).Grinding operation consumes about 60% of total power in cement plants, raw material grinding more than 30%, while coal mill used in cement plant consumes 3%, cement grinding about 40%.
cement plants would increase to 115-130 kWh/t cement in 2030 and to 115-145 kWh/t cement in 2050. _____ PROCESS OVERVIEW – Cement is a solid material made of clinker, gypsum and other additives. It is mainly used to form concrete, a conglomerate of cement, water, fine sand and coarse aggregates, widely used for civil engineering constructions.
The cement clinker grinding plant or cement grinding station acts as an individual production line while in the final period from the cement production course of action. Within the finished product time period, the cement clinker is ground by including reasonable mixing products and after that forms the completed cement.
